Abstract
Perfluoropolyethers having an average molecular weight higher than 390 and respectively having a kinematic viscosity lower than 8.5 cSt (at 20°C), and such as to distill by not more than 10% at temperatures lower than 140 °C, and by at least 90% at temperatures not higher than 260°C, or, in the case in which the perfluoropolyether does not contain CF-(CF<sub>3</sub>)CF,O units, having a viscosity lower than 18 cSt (at 20°C), and such as to distill by not more than 10% at temperatures lower than 140 °C, and by at least 90% at temperatures not higher than 280°C, are used as the only high-temperature and low- temperature working fluid in the Thermal Shock Tests to which the electronic components are submitted, and at the same time are advantageously used in other tests used in the electronic industry, such as the Gross Leak Test and the Burn in Test, allowing the operators in this field to use one single fluid for a whole set of uses.
